Battle to save Ozzy Osbourne’s life: Air ambulance medics were called to Black Sabbath singer’s Buckinghamshire mansion on Tuesday morning and spent two hours treating him before he died surrounded by loved ones

An air ambulance was called to Ozzy Osbourne’s multi-million-pound country home as paramedics battled to save his life, MailOnline can reveal.

The Thames Valley air ambulance landed in a field close to Welders House, the singer’s Grade II listed mansion on Tuesday morning at around 10.30am.

It’s believed that calls from Welders House had led call handlers to believe that the Black Sabbath singer’s life was in the balance.

A chopper was dispatched from Thames Valley ambulance base in Stokenchurch some seven miles to the mansion which is located close to the village of Chalfont St Giles, Buckinghamshire.

The crew were at the scene with Ozzie for around two hours, trying but failing to save his life, it’s understood.

News of the helicopter drama is the first insight into the finer details of the singer’s death.

It was announced by his family last night in a statement which read: ‘It is with more sadness than mere words can convey that we have to report that our beloved Ozzy Osbourne has passed away this morning. He was with his family and surrounded by love.’

Locals in the village of Jordans, which adjoins Osbourne’s home told MailOnline that they realised ‘something serious’ was taking place when they heard a helicopter hovering above Welders and then saw it land nearby.

A crew from the Thames Valley Air Ambulance was reportedly scrambled at about 10.30am 

It was seen taking off again at around 12.30pm.

One resident, who did not wish to be named said: ‘I went out to have a look and saw that it was landing close to Ozzy’s house.

‘All of us were talking about it and wondering what had happened. We immediately feared it may be for him as he was known to be in fragile health.

‘When we heard later that night that he had died it confirmed our worst fears.’

A spokesperson for Thames Valley Air Ambulance confirmed to MailOnline: ‘We can confirm that our helicopter was dispatched to provide advanced critical care at an incident near Chalfont St Giles yesterday.’

Ozzy’s 125-year-old country pile is surrounded by a 350-acre estate which he and Sharon bought in the summer of 1993 for an undisclosed sum.

Ahead of his arrival in the UK for his farewell concert in Birmingham three weeks ago it had undergone a major refurbishment which included a dedicated rehab wing, swimming pool and pond so that he could spend more time there as his health deteriorated.

Another local, Jane, also saw the Air Ambulance.

She told MailOnline: ‘I was out walking when I saw the helicopter landing close to Welders and realised something serious was happening….

‘Ozzy Osbourne was quite a character and we’ll miss him.’
